Just went for a week at the end of October and had a great time! (Except we got the "edges" of the hurricane one morning and they closed the park for 1/2 day!)
Crowds were fairly light - the only long wait for any ride was for Soarin' (which happens no matter what time of year it is). I think it's because it's such a new ride - it might taper off somewhat when the ride is not such a novelty. [Have never experienced those long lines for Soarin' over California at Disney's California Adventure!]
Went to the F&W festival every day during our trip - lines were very bearable. Still recommend making ADRs as far in advance as possible - tried to get a walk-up at Le Cellier and couldn't get in until 9:00 p.m.
Just remember it's hurricane season! It didn't stop us from going, but did cause us some anxiety, because at one point the hurricane was scheduled to go through the area the same day as our arriving flight. Luckily, the storm slowed down and didn't hit until we had been there two days - and it was pretty mild. But you never know!
